    Abstract: 樂高堆砌的演算法一直以來在電腦圖學領域中佔有一席之地,相關的論文研究亦隨年份穩定累積,且扮演立體結構原型的創意發揮工具。然而在過去的研究中,大多數的論文雖以3D堆砌為最終目標,卻依然脫離不了傳統的格狀堆積方式(Voxel-based Modeling)。本研究嘗試引入SNOT(Studs Not On Top) 的斜拼技巧,從可動骨架的製作為出發點,創造出一副具有造型延展性的樂高骨架,不再將樂高堆積的方向限制在傳統組合方式,且配合可動關節,加強可動性。
    The LEGO stacking algorithm has always played an important role in the field of digital Fabrication. The related researches have also accumulated steadily with the year. However, in past research, most of the designs are still following the traditional Voxel-based Modeling method. Our study attempts to create a LEGO model from a new perspective, which is SNOT(Studs Not On Top). Our research attempts to create a movable skeleton that can add other LEGO parts around it, which no longer limits the direction of LEGO stacking with the traditional designing methods.
    Our research uses a 3D model as the initial reference material, combining the algorithm and the information of the virtual skeleton drawn by the designer. We propose a LEGO skeleton assemble algorithm considering graph theory, topology, and three-dimensional structure related operations. The skeleton is composed of modular joint parts with mobility, stability, and expandability to meet the needs of different shapes, structures, and proportions. The final output of the skeleton results, the format of which matches the specifications of the LEGO Digital Design Software, to facilitate users to perform more editing. Such as the installation of parts and estimated parts quantities.
